BOY L. :BOS'WELL AND HARRY E. MARTIN, OF TATE, NEBRASKA.

OLLAPSBLE SHIPPING-@ASE Specication of Letters Patent.

Patented May 29, 1917.

To all whom it may concern:

Be it known that we, ROY ill. BoswnLL and HARRY E. MARTIN, citizens of the United States, residing atk Tate, in the county of Fawne'e, State of Nebraska, have invented certain new and useful improvements in Gollapsibie ShippingCases; and we do hereby declare the following to` be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich" it appertains to make and use the same.

This invention relates to im rovements in shipping receptacles, and is irected more particularly to collapsible cases adapted for use inthe transportation of eggs or other articles.

An object of the present invention resides in the provision of a collapsible shipping case embodying means of novel construction and arrangement for securing it in set-up position.

A further object of the invention is to provide a case which'may be conveniently folded in small compass for storage or shipment.

The invention further proposes a fastening means of novel construction and application for assembling the various portions of the case.

With the above and other objects of similar nature in view, the invention consists n the construction, combination and arrangement of parts,set forth in and fall ing within the scope of the appended claims.

In the drawing:

Figure 1 is a plan view of the blank from ,which our improved case is formed;

Fig. 2 'is a perspective view of the case illustrating the manner of assembling the same;

Fig. 3 is a plan view of the case 1n set-up Fig. 4. is a transverse section taken onlthe line 4 4 of Fig. 2;

Fig. 5 is a detail section taken on the line 5--5 0f Fig. 5;`

Fig. 6 is a detail perspective view of one of the fastening devices;

Fig. 7 is a horizontal section through the case with the partition and strengthening member in place; and

Fig. 8 is a detail perspective view of one of the elements of said member, 'the other element being .indicated in dotted lines as interlocked therewith to illustrate the position assumed by the parts when placed in the case.

Referring now more partculariy to the accompanying drawing, there is illustrated in Fig. 1 the blank from which our improved case is formed, said blank consisting -of a substantially rectangular body l0 provided with parallel fold lines 11 dividing the body into a central portion adapted to form the bottom 12 of the case and side portions adapted to be disposed at right angles to the central portion to provide the side walls 13 of the case.

Formed at the ends of the sideportions 15 and defined therefrom by the fold lines i4, are flaps 15 `adapted 'to be folded to lie in overlapped relation to provide the ends of the case. Certain of these iiaps are'provided with spaced series of openings 16 while the remaining flaps are provided with spaced pairs of openings 17. In foiding the end flaps to form the ends of the case, thosek provided with the openings 16 are disposed inwardly of those having the openings 17,

while the latter openings are disposedy in registration with corresponding pairs` of openings 16.

Formed at the ends of the central portion 12 of the body and defined therefrom bythe fold lines 18, are iaps 19 foldable to over# lap the end flaps 15 and provided with spaced pairs of elongated openings 20 registrable with the corresponding openings in said Haps. Formed on the outer transverse edge portions of the flaps 19 and defined therefrom by the fold lines 21 are iaps 22, foldable to close the top of the case. Formed on the outer longitudinal edges of the side portions 13 and defined therefromby the fold lines 23, are liaps 2li foldable vto overlap the flaps 22.

These aps 24 are similarly provided adjacent their ends with elongated openings lie the end 28 and continued therebeyond f positions, the end 2I'being` disposed to overtor insertion in the lower oi' the openings 16 in the related series. fhe apsare thus held against accidental displacement, while to collapse the case said strips may be conveniently disengaged from the aps by ref versing the above described operation.

I Connecting the strips 26 at each end of the case, is a bar 29 secured as at 3Q to the interlfmediate portions of the strips, .and consti-` tuting a suitable handle by which the case maybe conveniently carried when in set-np position. fF or 'dividing the case into cem-` pertinents yas illustrated in Fig. "i" of the draw ng5ti-iere is provided a combined par- .y @nya-lengthening member 33 consistreferablyI of two similarly formed strips" lff-iber or pulp' board interlo'cked one withthe other. The intermediate porltion; f'each stripis slotted transversely' from onfsideas" indicated at'36 while its ends'37 are bent oppositely at" right anglesl from the intermediate portion. In assembling the' strips, the intermediate or slotted portions are disposed'with the slots 36 openl ing toward each other and are brought together in interlocked relation as shown most clearly in -rFig. 8. The intermediate' por-t tions 35'thus provide the partition which divides the case into compartments while'the vends 37 of each strip coperate. with the adjacent ends of the other strip to reinforce the side walls of the compartments thus produced. The eggswill in this manner be protected on all sides by a double thickness of board, possibility of breakage being cor respondingly reduced, while the case itself l' will be materially strengthened to resist the hard usage to whichit may be ibi-lasted. With the partition and streng-the; ng :nember in position, suitable fillers and flats (not shown) may be placed in the case and filled with eggs in they usual manner after which Athe iaps 22 and 24: Vare folded to close the case.

In order to'lock the case, there is carried 'by'each of the flaps 22, a strip 3l intermediately secured to, the flapas at 32, with its ,endsbent upwa-rdand adaptedfor insertion through corresponding openings After insertion of said ends through the openings,-

they are bent toward each other as clearly illustrated, one ofsaid ends'1being longer than-the other and aaaptedto overlie the same with its'terminal removably inserted in the related openingofthe shorter end,

Thus in order to gain access to the case,v

it is onlytnecessaryto'withdraw the longer end from lthe opening and then bend the end ing p .upwardlyl vto permit of disengagement of the flaps 24. y

vNVhat is claimed is;

1. 4In a collapsible shipping case, the combination with overlapping flaps providing a `wallof the case, said aps having pairs of registering openings, and one of the aps being further formed with 'an opening in vertical alinement with said registering openings, of a locking strip having its ends bent and inserted through the registering openings, one of, saidfends 'being further -bent to overlie the other end thereof and extending therebeyond and entering the alin- 'ening-with its extremity disposed betweenthe flaps.

2."A 'collapsible shipping" case including bottom,I side and end Walls, naps carried by the end walls removably xiolded to close the "top loffthecase, iiaps carriedby the side wallsremovably olded'to 'overlap the rsty named naps-and provided withtransversely aline'd openings and flexible locking strips secured between their ends to the first named lapsand havingtheir ends `removably inserted' through corresponding openings in the last yI laltlled aps, one end'of each strip being bent to ov'erlie the other end thereof and -havingits extremity disposed in the together said end flaps and bottom wall flap, yand al member connecting the strips outwardly of the iaps and forming a handle for the case. l

4. In a shipping case, the combination withoverlapping wall portions having reg- .'105

isteringopenings therein, of a locking element'ineluding-a handle portion and spaced ieXible strips connected by and secured between their ends to said handle portion, the ends of the strips being removably inserted through said registering openings and bent to lock said wall portions in overlapped re-` lation,

In testimony whereof, we aihx our signatures in thepresence of two Witnesses. f
